Each bar provides 15 g of protein, which contributes to the growth and maintenance of muscle mass and the maintenance of normal bones. The light, puffed texture makes them easy to enjoy at any time of day, whether before or after activity, or as a snack between meals.

Former track athlete and dietitian Albert Matheny launched Promix Nutrition in 2011 to create better, cleaner options for performance nutrition. Working closely with athletes, he developed formulas grounded in ingredient integrity, research, and safety. Promix products are built around what’s needed — and nothing more — with no artificial additives, gums, fillers, hormones, GMOs, gluten, soy, or antibiotics. Every formula is developed using current research, approved by in-house dietitians, and independently tested in 100% GMP-certified facilities. The result is clean, straightforward supplementation designed for people who care about exactly what they’re putting into their bodies.
